摘要
根据两种调光器的原理和应用范围 ,分析了误用的危害 .结合实例总结了两种调光器应用于不同阻抗特性可调光照明系统时的正确选择 .就前沿相位控制调光器和后沿相位控制调光器与阻抗特性各不相同的一些负载的匹配进行了研讨 .
As the high frequency converting technology is applied in some new dimmable electronic lighting system, the previous leading edge phase control dimmer can not adapt to these new systems. A trailing edge phase control dimmer has been developed successfully. The principle and the applications of two kinds of dimmers were discussed. The danger caused by misuse was analysed. Some examples of their application were shown, and a conclusion was derived that the correct selection of two kinds of dimmers used for dimmable lighting system which has a different impedance character.
